Indeed, it is possible to check the area for coverage less than 3% (for example), but in the report, the whole image area is marked as erroneous, not individual spots. Also, if one ink has 1% coverage and another has 4% it will be reported as 5% coverage, which is not correct. The check needs to work on channel by channel basis.

Is it possible to achieve something like in the previously attached image, not just a report?
